l'o all whom it may concern: A

Be it known that I, SAMUEL R. BAILEY, of Amesbury, in the county ofEssex and State of Massachusetts, have Vinvented a new and usefulImprovement in Carriage-Axles, which will, in connection with theaccompanying drawings, be hereinafterffully described,and specificallydened in the appended claim.

In said drawings, Figure l is a longitudinal central section of the axleand a hub in which it is inserted. Fig. 2 is a transverse sectionthrough the axle and box, taken as on line l, Fig. 1. Fig. 3 is a frontelevation of the outer cap. Fig. 4 is a longitudinal central section ofthe front portion of the box,the caps, and nut, slightly modified fromthose shown in Fig. l, with the axle shown in elevation.

In said drawings, A represents a hub, introduced to show relations ofparts, in which lis secured the box Cin which is arranged the axle B,the principal portion of the (bed of which is broken away. In lthe armof said axle is the axial hole or bore a which terminates at collar qand is vented at b, which vent is closed by screw c; an loblique hole dleading from the short shallow groove een top of the axle to said ventb.

,At the front or Quter end of box C a cap D is firmly secured upon it,preferably by a screw thread as shown, and when the box is secured inhub A and cap D has been secured on the box the latter is then firmlysecured to the hub by screws shown by dotted lines in Fig. l, and theholes for said screws are shown in Figs. 3 and 4f. Said cap D is formedwith cylindrical partf. This is secured upon box C, with an internalflange g that bears against the end of the box, an external flange hthrough which said screws pass and a cylindrical part i to which thefront cap E is secured.

In Fig. 1, the nut F is threaded axially in B and it is formed with anaxial passagethat terminates at the small transverse passage t as shownin Fig. l, and .the axle may if desired have a small hole w formedthrough it.

yIn Fig. 4, cap D is at part z' threaded on the outside and part j ofcap Eis threaded to pass over part t', and nut Fis threaded upon itsinterior to engage part G of the axle.

At the rear end of box C is arranged a packing as shown for the merepurpose of arresting the outward flow of oil; but both the outer andi'nwardpwear of the axle are arrested by nut F which bears upon packingm, which may havea slight spring by bearing in cap E at its peripheryonly as shown in Fig. l, or the nut may have a/solid bearing as shown iny Figfl, whicharrests the inward inclination of the wheelgand thebearing between flange g of cap lD and the adjacent part of nut Freceives the wear caused by the outward inclination of the wheel; andwhether nut F is threaded in the axis of axle B or is threaded thereon no oil ever escapes at the front of the Wheel. It must all pass thelength of the box and -escape at the rear end. When the axle is formedwith passage c the oil is introduced in passage b and escaping throughpassage t in nut F it passes to the rear of box C and finally escapes atthe rear end thereof if at all.

When nut F is threaded upon axle B, it

bears solidly againstthe extreme end of the axle instead of against ashoulder formed upon/the axle at the inner end of part G. When a collaras D is secured upon box C,

and it is also secured to hub A, then said box.-

can be formed without us and can be turned perfectly cylindrical itsentire length and can be fitted and forced into hub A, with the requiredpressure, and it is heldfsecurely in position in the hub.

By forming cap D with an .internal liange g, said cap bears against theentire outer end of box C and nut F has abearingagainst said flange muchwider than if saidvnut and box were formed in the usual manner.

Having thus described my invention, what SAMUEL R. BAILEY.
